That all depends on the assumption that the P&S is NOT a blow-up from the widescreen, which probably isn't the case. In the 80s and 90s the 4x3 transfers were minted straight from a print because this was 99% of the market, but in the DVD era where 4x3 is not liked I think they are more often than not just blow ups from a widescreen master. Even on Fox's "what is widescreen?" feature on the Die Hard 5-star DVD from 2001 they show the fullscreen process as derived from the widescreen master and thus losing resolution.
